This is not just a problem for philosophers of religion. It is equally a problem for sociologists of religion, psychologists of religion, and other social scientists—economists, political scientists—and for those few brave neuroscientists and other biologists who have decided to look at religious phenomena with the tools of their trade. One of the factors is that people think they already know everything they need to know about religion, and this received wisdom is pretty bland, not provocative enough to inspire either refutation or extension. In fact, if you set out to design an impermeable barrier between scientists and an underexplored phenomenon, you could hardly do better than to fabricate the dreary aura of low prestige, backbiting, and dubious results that currently envelops the topic of religion. And since we know from the outset that many people think such research violates a taboo, or at least meddles impertinently in matters best left private, it is not so surprising that few good researchers, in any discipline, want to touch the topic. I myself certainly felt that way until recently.
These obstacles can be overcome. In the twentieth century, a lot was learned about how to study human phenomena, social phenomena. Wave after wave of research and criticism has sharpened our appreciation of the particular pitfalls, such as biases in data-gathering, investigator-interference effects, and the interpretation of data. Statistical and analytical techniques have become much more sophisticated, and we have begun setting aside the old oversimplified models of human perception, emotion, motivation, and control of action and replacing them with more physiologically and psychologically realistic models. The yawning chasm that was seen to separate the sciences of the mind

Research is expensive and sometimes has harmful side effects. One of the lessons of the twentieth century is that scientists are not above confabulating justifications for the work they want to do, driven by insatiable curiosity. Are there in fact good reasons, aside from sheer curiosity, to try to develop the natural science of religion? Do we need this for anything? Would it help us choose policies, respond to problems, improve our world? What do we know about the future of religion? Consider five wildly different hypotheses:
